IMPROVEMENT IN APPARATUS FOR FORCING FLUIDS.

Specification forming part of Letters Patent No. 118,776, dated September 5, 1871.

To all whom it may concern:

Be it known that I, THOMAS W. MALONE, of Mason City, in the county of Mason and State of West Virginia, have invented a new and Iniproved Apparatus for Forcing Fluids; and I do hereby declare the following to be a full, clear, and exact description of the saine, reference being had to the accompanying drawing making a part of this specification, in which- Figure 1 is a longitudinal vertical section. Fig. 2 is a transverse vertical section.

This invention has for its object the production of an upward iiow of the contents of wells, whether of salt, oil, artesian, or ordinary species, or of cisterns, or of gas-tanks, or of coal-pits or shafts, by means of a forced current of air, as will be hereinafter explained.

In the drawing is shown a double-acting airpuinp, the cylinder A having a valve-covered inletport, a., at each end, and the piston B forcing the air alternately through the outlet passages b b into the connecting-pipe D, which is thus in receipt of a constant current. Thence the air passes through the pipe F down. into the receptacle containing the iiuid to be elevated. This may be an oil-well six hundred and fty feet, or more, deep, or a cistern or other reservoir. The lower end of the pipe F turns up and opens into an iron, wooden, or copper tube, G, that runs down to any required distance into the iuid. In an artesian well the pipe F will necessarily be Wholly inclosed within the tube G, but in a cistern, coal-pit, or other more enlarged space, the pipe F may be outside of the tube G, as shown, except as to the turned-up lower end of the pipe which opens into the tube. The aircurrent issuing out of the pipe F into the liquid contained within the tube G displaces the latter, causing that part of it that stands above the lower end of the pipe to flow upward, and the rest to follow in the wake of the upper part. Hence a continuous iiow issues out ofthe top of the tube G through the discharge-pipe H. This apparatus may be applied to a tank containing illuminating-gas for the purpose of causing the saine to flow to the various gas-burners.

Having thus described my invention, what I claim as new,and desire to secure by Letters Patent, is

In cornbin ation with an air-pump of the withinof the pipes F and G, as and for the purpose set forth.
